reverse a list of chained elements
Pointer to a chain_list to be reversed
function allows to reverse the order of the elements of
. It means that the last element becomes the first one,
the one before the last one the second one, and so on.
- remark :
all mbk structures have for first field the NEXT field, so, with
appropriate cast, one can reverse any mbk list. Let's notice that nothing
in the C language description demands a structure to be defined in
memory the same way its members are defined in C. But all compiler do it
this way now a day.
Let's hope it will continue!
reverse returns a pointer to the head of the reversed list.
p->LOCON = (locon_list *)reverse((chain_list *)p->LOCON);
